ap liemon m January 3, 1921. "Serial No. 434,630.

To all whom it may concern: Be it known that I, JOSEPH GALAMB, a citizen of the United States, residing in the city of Detroit, county of Wayne, and State of Michigan, have invented new and useful Improvements in a Vibrator Assembly' for Electrical Circuits, of which the followin is v a specification.

'lhe o ject of my. invention is to provide an improved vibrator assembly for electrial circuitis of simple, durable, and inexpnsiveconstructiom I Tn connection withthe use of vibrators for electrical circuits, and more especially inconnectionwith the use of such vibrators withthe coilfassemblies used in the ignition systems of internal combustion engines, it has been found difiicult to properly insulate supports for thecontact members in a convenlent and readily, made formof device, and it has also been diflicult to so construct these devices that'they may be readily assembled upon the coil boxes used in connection with ,thecoils of the internal combustion engines,'asthe supports for the contacts are usually'secured to the coil box independently of each other.

,.With the foregoing explanation in mind, it is a 'further object of my invention to provide novel means for insulating the two contact points of the vibrator assembly from each other and to provide in combination with such insulating members, novel and convenient means for fastening the vibrator $6 assembly together and to the coil box, these latter means also formin' the members for completing the electrica circuits through the vibrator members. e

A further object of my invention is to 40 provide a unit type vibrator-structure which may be adjusted when it is manufactured 1 i and simply fastened to the coil box without member 22, which extends forwardly from the lugs 19w position above the core 11, -at which'place it is enlarged to form an as distinguished from a type of vibrator further adjustment. i I V I I A further object of my invention is to .provide a unit' type of vibrator'structure structure which mfust be assembled afpiece at a time upon a coil box or other base.

I A further object of m'y invention is to:

ll!v provide a vibrator assembly which "may utilize -the means by which it is attached to, its su port to' formthe electricaliconriections or the 'circuits' ther'ethrou'gh.

' Wi'th' these and other objectsin v1ew, my

invention consists in the arrangement, combination and construction of the various partsof my improved device, as descrlbed in the specification, claimed in my claims, v

and shown in the accompanying drawings, in wh ch: I

Figure 1 1s a side elevation of a coil box for an ignition circuit having my improved '4 end elevation of the vi-' the pieces forming my vibrator assembly,

and

Figures 5 and 6 are enlarged detail sectionalviews illustrating the manner of electr'ically insulating my improved assembly.

' 'Referringto the accompanying drawings,

I have used the reference numeral 10 to in- -'dicate,"generally, a coil box for containing electrical coils which have a core member 113 extending from the top of. the box.

Threaded rods or bolts 12 and 13 extend upwardly from the coil box and are electrically connected with the'coils therein so that when a circuit is closed between'the rods 12 and 13, the circuit will be' closed through the rimary circuit of the coil within the box.

ounted'on the bolts or rods 12 "and 13 is a-base member for'my vibrator assembly, which is illustrated'in detail in Figure 4. This base member'has'ear's 14 and15 which 'tending'rearwardly from the base member haveopenings 16 and 17 therein designed to between the" ears 14 and 15 is a reed supporting lug 19 having a pair of threaded openings 20 and 21 therein. '"Mounted on this base member is a reed armature ztor the core'll. The rear end of the reed is perforated to receive screws Hivets maypbeflused instead of the screws, -if"desired. Itfwill be noted that the'feet 18 are bent" down from the cars 14 and 15, so'that the; .lug;19 is supported in posiltion' sfiaded somewhat above the top of the coil box 10 so that the tension on the-reed may bevari'ed b bendinfdhe-lug; 19-toward or away fromt 13 top 0 the'cevl bbx lOL Above the base member of my assembly is a bridge member which is provided Wit ears 25' and 26*, wh'ieh**have=o wings-therein to receive rods12 aiidlitl- T abridge nien'uher is bowed upwardly-interim 'ate'of the. ""extnsioir 27 which extends to 'osition above the free.

ears 25 and 26 andhas'a'forwl end of the reed 22 an the core 11. Beneath the forward extension27, on the bridge-menu beris a cushion springi28 which, carries con tact member 29. This cushion spring 28 is arranged to throw aw ay-fromtheaextension 27 slightly. andthe throw is limited byvaqlug 30, which extends through the cushion spring and is fastened 1 in -the extension' 27. A contact member, I isSecured tU-the top of the free end of the vibrator: or reed in position to co-act with the con-taet'memher 29. AJkriQb 35 maybe secured'-;to tlie bridge member for convenience-in handling thegsame, iii-desired. I l I I It -:will be' noted t the ears and -26 of the bridge member and the ears 14 and 15 ofthe base member each have oplenings therein designed to receive the bolts 12 and 13 respectively These :bolts 01' rods are r electrically connected with theterminals of the coils in; the coil box-- so that when a circuit isclosed therebetween then that a; circuit will be-closed throughl the proper-'coih For causing thejclosing of this circuit to be: completed through the contacts :29 and 31 when the latter: are brought together, I electrically insulate:- they-rod 12 from the ear 14 :and; consequently from the base membergland the ear-261mm the rod 13 thereb insrrlating: the bridge member fro'mthe atterrod. As the contactis carried by the bridge member and thacontact 31* is carried bythe'reed; whioh in turn is' connected with the I base, it Will be seen 7. that I bringing these contacts; together will complete the electrical cireuit between the rods 12 and 13.- The oontacts 29 and 31 areso brought t ethernormally; by; the resiliencyof the rec 22, :whieh =throws:seid contacts: together thereby? making the contaet nermallya completes W'hen, however, the contact is completed -th'e circuit is oompleted through on'e of themoils in -the coil box", thereby energizing; the; coil: and; core 1 1 te draw the reed -amly' from theqbfidige ing" of these contacts continuesindefinitely in the: manner we'll: in vibratorsas long as electri'eal current a is supplie'd tmthe coils:- H it is desired gto djusmheitorquer; of the: reed- 22; .4this m'ayl be abcolnpl'ished byi beading- 2 the: lug- 19: tevuaml the a tes 06- th'e cet'L-box oi' 1 The instillation" w may oi -the- ,nutsr w bridge and base members is accomplished ale-follows. Inconnection with the rod 13 insuldtiiiglwaehers 36ise1arate the1ear 26 from. the car 15 and insulate said members from each other. The washers are, howevemheld' together; held in position" to propefly''support the ear 2'6 and" held against the ear 15 by a sleeve 32 which has its 'endb en'tout and turned over the Washers 3 1 and ear 15 respectively. As this sleeve 32 contacts direct with the bolt 13 and with the ear 15 it will beseenth-at an electrical connection may be completed from the bolt13 totheear 15 and consequently to 'the base member. The rod 12 and the sleeve 32 surrounding that rod are insulated from the ear l and the basemember by the washers 3B and thesezparts are held 150+ gether by the turning over the sleeve 32 e ingthe manner illustrated in Figures 5;=and 6i In'this case it will benotedthatthe ear 25 of the'bridge/member contacts directly with the sleeve 32 thereby completingthe-circuit throughthe rod 12 to said bridge member.

From the v foregoingdescriptionit, will be 1 seen that the base, bridge, reed and insulatingvwashers may be assembled into a unitary structure and the lug 19: bent to givethe reed 22the groper tension before the device isassemble on the coil box. When his to be assembled thBI'SlBGVGS 32 are simply dropped down over the rods 12 and 13 and uts 34 are tightened 'gdown to hold the vibrator structure inplace.

From the foregoing description it will also be seen: that I have provided a unitary structure which may be readily attached to a coil; box and which utilizes the attaching means for completingthe electrical circuits.

This vibrator structure is especially adapted for replacements, as a: person without anyrexp'erience may. replace the vibrator structure on an old coil by. simply)- unscrewingthe nuts to remove the old vibrator,

slippingjthenew vibrator on over the'bolts 12 and 1 13,,-and then .tighteningdown the Some changes may made in, the barran-gement and construction of the various parts ofmy improved device without departing; from the spirit of the invention therein,- and it is any intention to cover by my claims such changesas maybereasoi'i- I ably 'ine l udedwithin-the scope thereof.
